1. The problem statement, all variables and given/known data We have the water electrolysis of ZnSo4 with soluble electrodes. How can we write the complete equation of it? 2. Relevant equations 3. The attempt at a solution I an only write: Anode: Zn->Zn2++2e Cathode: Zn+2+2e->Zn How should I write the total equation?
